STRAINING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 373,778, dated November22, 1887.

Application tiled March 5, 1887. Serial No. 229,779. (No model.) V V Toall whom/'it may concern:

Be it known that we, AMos KOPLIN, a citizen of the United States, andWILLIAM ORowE, a subject of the Queen of Great Britain and Ireland, andboth residents of Eddystone, Chester county, Pennsylvania, have inventedan Improved Straining Apparatus, of which the following is aspecification.

The object of our invention is to construct a simple and convenientapparatus for the automatic manipulation of straining-cloths which areused for the straining or filtering of such materials as the colors usedin dyeing, calicoprinting, and similar operations. It is the commonpractice now to manipulate these cloths by hand by uniting adjoiningcorners at opposite ends thereof into loops, hanging these loops on onehand so as to form a bag to con'- tain the dye, and then twisting andstraining the bag so as to force the dye or other material through themesh ofthe cloth, and thus filter the material through the cloth,leaving vthe dirt in the straining cloth or bag. This is not only a verylaborious operation, but requiresskilled labor. We have constructed asimple and convenient apparatus by which this straining of the materialthrough the cloth may be accomplished automatically, the machine beingdriven by steam or other power or by hand.

In the accompanying drawings, Figure 1 is a face View of our improvedmachine. Fig. 2 is a side view. Fig. 3 is a plan view. Fig. 4 is anenlarged sectional plan on the line l 2, Fig. 5. Fig. 5 is an enlargedsectional View of the gearing; and Fig. 6 is a plan view of thestraining-eye through which the cloths are drawn.

The machine consists of a yoke-shaped or other suitably-shaped frame, A,to be mounted on an open base, B,`and having a central back leg, A', sothatthe machine is somewhat in the form of a tripod. Passing centrallythrough the frame A is a vertical rod, D, having at its lower end ahook, d, on which the loops of the straining-cloth are to be suspended.The upper end'of this rod I) is threaded, as shown in Figs. 1 and 5, andthis threaded portion is adapted to a fixed nut in the eye a at theupper end of the frame. The portion of the rod D below its threaded endis guided in two crossprovide a feather, d, Figs. 1 and 5, adapted to acorresponding groove or seat in the wheel. Into this bevel-wheel gears awheel, E, Figs. 2, 3, and 5, on the end of-a short horizontal shaft, F,adapted to bearings in the frame, and having driving-belt pulleysff,Figs. 2 and 3, or a crank-handle where it is to be turned by hand.

At the lower end of the frame A is a crossbar, G, carrying a two-parteye-piece, H. One half kof this eye-piece is secured to the crossbar,while the other half is carried by a pivoted latch, h, of such-acharacter that the eyepiece can be readily opened for the introductionof the ends of the straining-cloth, and as.

readily closed and secured when the machine is to be putin operation.The straining-cloth,

with the contained dye or other material to be filtered, has its loopedends hung onto the hook d of the feed-rod D, as indicated by dottedlines in Fig. 1, and the neck of the bag thus formed is introduced intothe open eyepiece H, which is then closed. The shaft Fis then put inmotion so as turn the bar D to feed .it upward by the turning of thethreaded portion of the rod in the fixed t'eednut. The rotary motionimparted to the rod D simultaneously with the longitudinal motion gives,by the friction of the cloth against the eyepiece, the desired twist tothe straining-cloth, to force the dye or other material through the meshof the cloth to properly strain or lter the material as the bag isturned and drawn through the eye-piece.

We claim as our inventionl. Theherein-described straining apparatus,comprising a ixed eye-piece and a feedrod to which the straining-clothsmay be attached, and devices, substantially as described, for impartinga rotary and longitudinal motion to the feed-rod.

2. The combination of the-frame, having an eye-piece and a feed-nut,with athreaded feedrod adapted to said nut, and devices, substantiallyas set forth, for rotating the said rod.

3. The combination of the frame, having an eye-piece and a feed-nut,with a threaded feed- ICO f nut, with a threaded feed-rod adapted tosaid nut and having a hook to receive the straining-cloth, and a rotarygearwheel having a feather-and-groove connection'with said feedrod, allsubstantially as set forth. 15

In testimony whereof We have signed our names to this specification inthe presence of two subscribing witnesses.
